Accupro CL01310000MSC Drill Chuck 1/2-20 Threaded Keyed

Product Description

The ACCUPRO CL01310000MSC is a keyed drill chuck designed for threaded spindle mounting in drilling and boring applications. It accepts bit shanks from 3/64 inch (0.059 inch) up to 1/2 inch (0.500 inch), making it suitable for a wide range of drill bit sizes used in trade and production environments. The chuck uses a plain bearing design and is constructed from steel for durability under repeated use. Tightening is performed with the included K34 key. The 1/2-20 threaded mount is a common spindle interface found on drill presses and portable drilling equipment. This chuck is installed by machinists, tool-and-die technicians, and maintenance mechanics.

This chuck fits drilling applications in light manufacturing, maintenance, and shop environments where a threaded-mount keyed chuck is required. The 1/2-20 thread size is a standard interface on many benchtop and floor-standing drill presses as well as some portable drilling equipment. The 3/64 to 1/2 inch capacity range covers the majority of twist drill and step drill shank sizes used in everyday trade work. The steel construction and plain bearing design make it a straightforward replacement or spare for production and maintenance shop use.

Installation Notes

Installation is performed by qualified machinists or maintenance mechanics. Disconnect and lock out power to the drill press or drilling equipment before removing the existing chuck or installing a new one. Thread the chuck onto the spindle by hand first to confirm thread engagement, then tighten securely using the spindle wrench method appropriate to the machine. Refer to the equipment manufacturer's service documentation for spindle removal and chuck seating procedures.
